CHARLES H. MOORE, OF NEW YORK, N. Y.

WATER-CLOSET CISTERN.

Specification of Letters Patent.

Patented May 4, 1909.

Application filed January 23, 195. Serial No. 242,348.

To all whom it may concern.'

Beit known that l, CHARLES.; ll. MOORE, a citizen of the United States, residing at New York city, in the borough of Manhattan, in the county of New York and State of New York, have invented a new and useful Improvement in YWater-Closet Cisterns, of which the following is a specification.

The object of this invention is to provide a cistern for water closets or like iixtures that will. be simple, reliable and noiseless in its operation.

Another object of the invention is to provide a simple means for operating the cistern valve.

1n the accompanying drawings forming a part of this specification Figure 1 represents a central vertical section of the invention. Fig. 2 represents a cross section. Fig. 3 represents a cross section of the device that lifts and opens the discharge valve in the cistern, and is connected to the fiush pipe and forms a part thereof.

1 shows a cistern of the usual size.

2 is a valve seat Within the cistern and having;- a shank 3 extending through the bottom of the cistern and secured with a lock nut 4.

5 is the nut that secures the flush pipe to the shank of the cistern valve.

6 is the overliow pipe.

7 shows a disk of the discharne valve on the lower end of the overflow, and 8 is a thin iexible valve held to the under side of the disk 7 by a nut 9. This nut 9 has a concave shaped cross bar of depth enough to allow overflowing water to escape at each side of it and into the 'flush pipe.

10 is a stern on the cross-bar 9 that guides the valve to its seat through an aperture in the cross-bar made in the valve seat shank 3.

11 is a vessel open at the top and recessed at the bottom to encircle the disk 7 and is of sufficient de th to allow the valve to be lifted sonic ristance from its seat before it comes in contact with the under side of it.

12 is a portin the bottom of the vessel to allow Water to enter the vessel.

13 is a cover or valve over the port 12.

15 is a lever having a Weighted portion extending across the Width of the cistern so as to get an even bearing; at each side of the cistern without much friction on the axis of the lever, and to evenly distribute the necessary heft that is required to ovcrbalance the weight of the discharge valve, and get the Weight as near the axis of the lever as practicable, and by so doing the desired purpose of sustainingr the discharge valve up from its seat Without having to raise the said valve more than an ordinary distance from its seat is attained. This weighted portion 15 ol' the lever is arranged Within the cistern so that the heaviest part of it is always on the side of its axis farthest from the outlet valve, and is held in the position above the axis wholly by the weight of the discharge valve and fittings attached thereto, but when the lever 15 is operated by the usual pull or other means, the Weighted portion of the lever increases in distance from the vertical line x of the axis of its journals 16 for every degree it de scends from the said position it is shown in when the discharge valve is closed. Therefore for every degree it drops from the normal position it occupies when the discharge valve is closed, the leverage increases and exerts a greater upward pressure or lifting;l force on the discharge valve until its heft finally overbalances the Weight of the dis charge valve and keeps the said valve open while the Water is discharging from the cistern. When the cistern is nearly empty, the Weight of the water in open vessel 11 will overcome the leverage of the weighted portion of the lever 15 and will automatically close the discharge valve and lift the weighted end of the lever to its normal upper position.

14 represents an arm extending* out from the lever 15 and forms a part thereof, and is connected to the discharge valve and overflow pi e 6. This overiow extends through the dislf and discharge valve 7 and is carried by the lever when the discharge valve is opened.

16 represents two journals, one at each end of the lever 15, each of these two journals are fitted loosely in a journal box 2O secured at each side of the cistern, so that there Will be only a slight amount of friction.

17 shows an arm extending out from the lever 15 in the opposite direction from which the arm 14 extends. This arm 17 rests against the top of the cistern when the discharge valve is fully opened. Instead of operating the lever 15 by a chain or other pull connected to the arm 17, I may use the following devices. 13 is an adjustable litting on the upperI end of the lifting rod 19. 19 is a rod operating in the flush pipe 33. On the lower end of this rod 19 a blade 34 is screwed (by neference) and is entered into the receptacll 22 through two spaces 35 made in the flange 23 within the receptacle. 'Vlie flange 23 is to support the end of the blade 34 when it and the rod are put into the flush ipe and prevents the blade from entering t 1e receptacle other than the right position, and after the blade is in place the flange prevents it from turning or in any way o"etting displaced. The lower edge of the blade 34 rests upon the lever 27. 21 is a branch or inlet in the side of the receptacle 22. 25 is a projection within the branch 21 against Which the arm 30 of the lever 27 abuts when the handle is turned a certain distance in lifting the cistern valve, and prevents the lever 27 from being turned completely around. If this arm 30 is not used the flange 23 will revent the lever 27 from being turned comp etely around. The lever 27 where the blade comes in contact with it, is shaped so, that when the Weight of the rod 19 and blade 34 are upon it when the discharge valve is closed the handle 32 will be turned to the same positive angle with the fiush pi e at each operation. 23 is a Harige on the ever 27, 29 1s a washer between the flat surface of the flange 23 and the inner flat surface of the cap 26, and 31 is a spring` that abuts against the neck of the cap 26 at one end and against a shoulder on the handle 32 at the other end, and this spring compresses the washer 29 between the fiange 28 and the cap and prevents any leakage of water through the opening in the cap that the stem of the lever 27 operates in.. 32 is the handle.

There are several small details in the receptacle 22 that could be made different without departing from the spirit of the invention, so I do not wish to be confined to any exact construction.

In o eration, when the handle 32 is turned partial y around, the lever 27 within the receptacle and connected to the handle lifts the rod 19 and cistern valve and allows the heaviest side of the lever 15 to turn to a position where its heft keeps the cistern valve up from its seat while water is discharging` from the cistern. Upon releasing the handle 32, the heft of the rod 19 upon the lever 27 automatically turns the handle 32 t0 a certain position at each operation, and rests upon and retains it in the said position until the next operation` When Water has ern tied from the cistern to a certain distance elow the top of the open vessel 11, the Weight of water in the said vessel in addition to the heft of the cistern valve and overfiow, turns the Weighted portion 15 of the lever back to the position Where the cistern valve is heavy enough to seat itself' and also hold the weighted lever 15 in a position above a horizontal line ol its axis.

The advantages are simplicity, ciseapness and noiselessness in operation.
